Interior lights not working/new cd deck wont work

[Ranjah]

Hey everyone, my interior light dont work - Dome light, clock, stereo, however the lights behind the MPH, gas, whatever that area of the car is called, i checked the fuses they all looked good no burns or breaks, anyone know what might be the problem? Also i just hooked up my new cd player which i figured wouldnt work because none of the other stuff works, and i was right. So if anyone has any idea what could be up with the interior, like a plug of some sort or maybe the fuses even tho dont appear to be bad still are can give me a heads up it would be greatly appreciated

Time to get a wiring diagram and a test light. Use a highlighter to trace the affected circuits. Look for a common point of failure and start testing.
